CDCM1802RGTT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the clock and analog circuits. The datasheet provides a recommended PCB layout, but it's essential to follow good PCB design practices to minimize noise and ensure optimal performance.
  • To optimize the clock signal, use a high-quality clock source with low jitter and a stable frequency. Ensure the clock signal is properly terminated and routed to minimize reflections and noise. Additionally, use a clock buffer or repeater if the clock signal needs to be distributed over a long distance.
  • The CDCM1802RGTT can tolerate a maximum frequency deviation of ±50 ppm. Exceeding this limit may affect the device's performance and accuracy. It's essential to ensure the clock source frequency is within the specified range to maintain optimal performance.
  • The CDCM1802RGTT has a maximum junction temperature of 150°C. Ensure good airflow around the device, and consider using a heat sink or thermal pad to dissipate heat. Avoid blocking airflow or using materials with high thermal resistance near the device.
  • The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD). Ensure the power supplies are stable and within the specified voltage range before applying the clock signal.
